The amendments, according to sources, correspond to issues including setting up a mechanism for dispute resolution between states or between states and centre and removing the 1 percent inter-state tax.

Finance Minister Arun Jaitley briefed his party’s members about the bill at the meeting of BJP’s parliamentary party on Tuesday morning.

Sources said Jaitley asked the members to read and understand the bill before it is taken up.

Both the BJP and the Congress have already issued a whip to their members making it compulsory for them to be present in the house on Wednesday when debate and vote on the GST bill are expected.
